from workspace to m.file

Hello. I want to take a variable from workspace to m-file. After I will process this variable and I will send to simulink. Could you help me please?

if your m file is just code (not a function) the variables are in the same scope as the worspace, you just need to call them like you do in the workspace, if you are inside a function you should provide the variable as argument to the function or use fun=evalin('base','funname') inside your function code to get the variable value from the workspace.

I take this error. I use parfor loop. cr is a variable from simulink to workspace via "To Workspace" block. What should I do?

"??? Error: MATLAB cannot determine whether "cr" refers to a function or variable.

See Parallel for Loops in MATLAB, "Unambiguous Variable Names".

Error in ==> parfor_deneme at 6

parfor idx=1:10"

[Paulo Silva]

perhaps you are trying to use a variable that's not created yet, To Workspace only creates the variable after the simulation is done.

I simulate my model via parfor loop. For this reason, now I do not know What should I do?

[Paulo Silva]

I never used parfor loops and have no clue what you are trying to do so unless you explain what you are trying to accomplish I can't help more.

I try optimization my model via parfor loop. I want to do Define the system I would like to optimize in Simulink and some measurement of quality of the solution based on the outputs of the simulation. I have to Use MATLAB workspace variables to define the parameters of the system that are changing, including initial conditions or input signals to the model. Could you help me please?

%initialize inputs

%loop x times or until some result if found

%start simulation and wait until it ends

%analyze simulation output and store info

%prepare inputs for another simulation

%return to start of the loop

You might find it useful to read the documentation on Running Parallel Simulations. There is also Solution #1-6GRUQ3 that describes the broader usage of Parallel Computing Toolbox with Simulink.
